Submission doc.: IEEE /1064r0 September 2015 Jarkko Kneckt, NokiaSlide 1 Long Range, Low Power Design Criteria Date: Authors:

Submission doc.: IEEE /1064r0 September 2015 Jarkko Kneckt, NokiaSlide 2 Abstract The submission discusses about design criteria for the Long Range, Low Power (LRLP) [1].

Submission doc.: IEEE /1064r0September 2015 Jarkko Kneckt, NokiaSlide 3 Introduction LRLP targets to improve WLAN transmission reliability and range yet not being adverse to other WLAN systems [2] LRLP key technical components discussed in [2]: Ultra low power consumption Communication range extension Coexistence with deployed WLAN networks

Submission doc.: IEEE /1064r0 Design Criteria for LRLP Ultra low power non-AP STA Operate with small size batteries (e.g. coin cell) Simplicity Light-weight non-AP STA protocol Power consumption and complexity burden carried by AP Enables simple non-AP STAs Reliability Improved coverage edge performance Coexistence with legacy WLAN Mechanisms for Sub20MHz operation Slide 4Jarkko Kneckt, Nokia September 2015

Submission doc.: IEEE /1064r0 Ultra Low Power for LRLP Non-AP STA operation using sub 20MHz bandwidth Spectrum efficient MAC Non-AP STAs could be grouped in frequency and time in an efficient way exploiting OFDMA Protocol overhead (signaling, headers etc.) minimized Slide 5Jarkko Kneckt, Nokia September 2015

Submission doc.: IEEE /1064r0 Backwards compatibility considerations Non-AP STA need not to support HE/Legacy In order to keep device requirements minimal AP that supports LRLP also supports HE/Legacy Minimum requirement for AP would be the ability to protect LRLP transmissions from HE/Legacy transmissions and vice-versa Slide 6Jarkko Kneckt, Nokia September 2015

Submission doc.: IEEE /1064r0 Summary LRLP non-AP STA supports ultra low power operation LRLP AP has both HE/legacy and LRLP modes to ensure WLAN coexistence Slide 7Jarkko Kneckt, Nokia September 2015
